In higherpair plane transmission, it is important to determine the curvature radius of the member.
平面高副传动中，如何确定高副元素的曲率半径是一个很重要的问题。

Kinematic analysis is carried out for the first time on constant-breadth arc CAM mechanisms with oscillating flat-faced follower by the method of replacing higherpair by lower pairs.
采用高副低代的方法，首次对平底摆动从动件等宽圆弧凸轮机构进行运动分析。

The two elements of a lower pair have theoretical surface contact with one another, while the two elements of a higherpair have theoretical point or line contact (if we disregard deflections).
